Dual-focused

The ability to cast atleast one spell.

Countless hours have been spend training your mind to maintain focus on concurrent incantations, taxing a the process may be.

• If you attempt to cast a spell that requires concentration while already concentrating on an existing spell, you canmaintain concentration on both spells simultaneously. You must spend a standard action each subsequent round on maintaining this concentration or lose concentration for both spells.
• At the end of each turn where you have two spells you are concentrating on, you must make a Constitution saving throw (DC equals 10 + the number of complete rounds you've been concentrating on two spells). On a failure, you lose concentration for both spells, and take 1D4 Psychic damage for each level of the two spells. You can drop concentration on one of your spells during your turn as a free action to avoid this saving throw. Any time you would be force to to make a Constitution saving throw to maintain concentration due to taking damage, the DC equals 10 + both spells' levels combined or half the damage you take, whichever number is higher. On a failure, you lose concentration on both spells, and take 1D4 Psychic damage for each level of the two spells
